Help: Downgrading from Vista 64-bit to XP Pro.

I need to downgrade our new Dell Inspiron 530 from Vista to XP Pro, so that I can connect it to our server. When I try installing XP Pro it tell me that something is blocking the install, but it won't specify what the block is. I would appreciate any assistants I can get in solving this problem.

Thank you for responding to my plead for help. There are no external devies connected to the system. I am trying to install XP Pro by restarting the computer with the CD in the drive. The screen come up with the install option and when I push install it says to the effect that, it's being blocked because it was any older version then what is already on the computer. How would I go about getting around that problem.

You need to (quick-) format the hard drive first Angela, such that you get rid of Vista completely, before you install XP Pro

From experience, I've found that: “Beautyis in the eye of the beer-holder”!!
